A recent Youtube Web update has added a canvas whenever the seek bar is visible, an HTML5 canvas pops up. This was not asked for and not needed. If you disable canvases for privacy, this will cause a horrific red bad to cover half the screen until you hide the seekbar. Canvases can be used for fingerprinting, which I’m sure Google is doing here.
Wait… so the red lines are added ON PURPOSE to deliberately degrade experience, and are not a side effect of having Canvas disabled?
Maybe, I don’t know if it was on purpose. But the red lines are the red-fade-to-pink effect of the progress bar I believe, and I have not found a need for such a feature, so they might be using this feature as an excuse to claim the need of canvas.
Sure sounds like it’s just an excuse, since it worked swimmingly before the canvas claim.
